To all whom t may concern:

Be it lrnown that we, Roenes T. STAFFORD and FREDERICK A. BALLOU, J r., citizens of the United States, residing at Rumford and Providence, respectively, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Pins, of which the following is a specification.

This invention relates to that class of jewelry known as pins and also to the pin stems on these pins by which they are attached in desired position; and the object of this invention is to so shape the pin stemy that when adjusted into operative position on its pin it will grip and bind the fabric engaged by it against the pin body to perform a double function which is that of binding the pin body in position on the fabric to prevent the pin from lopping or tipping over on its edge out of its proper or most attractive position, and secondly to serve as a fulcrum to tension the pointed end of the pin stem in theV catch to prevent the point from being inadvertently unlatched therefrom.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings Figure l is a front view of a bar pin to which our improved pin stem is attached.

Figure 2 is a side elevation of the bar pin with its pin stem locked in operative position with its middle portion engaging the` back of the pin body.

Figure is a side elevation of our improved form of pin stem.

Figure 4 is an enlarged end sectionron line 4-4 of Figure 2.v y

Figure 5 is a side elevation illustrating our improved pin as applied to fabric which is shown in dotted lines as being bound by the pin stem against the back of the pin body.

In many instances particularly in the case of long and somewhat heavy bar pins, especially those set with gems, when pinned into thin, sheer fabric with the ordinary straight pin stem, the weight of the bar or body naturally causes the pin stem to rotateaxially in its unsubstantial support and permit the bar to tip down on its side or edge rthus hiding the handsome jewels and naturally detracting from the `beauty of the pin, to obviate which diiiiculty our improved pin stemis provided with a portion intermediate its ends, bowed inwardlyjtowards or in Contact with the back of the pin body to bind the sheer fabric against the back of the body so tightly as to prevent the ypin stem from relative axial rotation in its fabric thus retaining the bar firmly in its set or most attractive position; andthe following is a detailed description of one embodiment of our invention lith reference to the drawing, 10 designates the pin body which may be of any desired form or shape such Vfor instance as a cuff p in, brooch, or any other style of pin to which a pin stem l1 is attached for connecting the pin body to the clothing of thev wearer or to any other support. Our improved type of pin stem is preferably bow shaped that is its middle portion 12 is curved inwardly towards the back4 of the .pin body to come very close to or actually contact therewith and to press and bind the fabric or material engaged thereby against this portion of the body of the pin when the pointed end 13 of the pin stem is caused to enter its'catch 14, which construction performs two functions: First, the fabric through which` the pin stem is passed is bound against the body of the pin thus pre` venting the pin from tipping over on its side ror edge; and second, the contacting, intermediate portion of the stem causes the pin body to serve as a fulcrum to tension the pin stem-relatively close kto its catch and to exert the maximum binding pressure on the pointed end of thisl stem causing it to be retained in its catch, which advantageous effect cannot be obtained with the old style pin stem where the fulcrum is at the jointed portion 15. f

. Our improved construction of pinstem is very simple and practical in construction and effective inits operation and by its use the above set forth desired effects are attained and that without Vaffecting the ease of inserting of the pin stem into the fabric ly towards the construction illustrated, but We desire it to be understood that We reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claim.

We claim:

A pin comprising a body member having a back With a surface disposed substantially in a single plane7 a pin stem pivotally mounted thereon and having a catch to receive its free end, said pin stem being bowed inwardly to provide an elongated bearing surface to bind its supporting fabric against said body back surface and also to tension said free end in its catch.

In testimony whereof We affix our signa tures.
